Tarpaulin knowledge small science

Covering tarpaulins is a compulsory course for truck drivers. To choose a tarpaulin, you need to do your homework in advance. How to choose a tarpaulin, what materials are it divided into, and what are its characteristics? Let's learn together today.

1. PVC tarpaulin

Mainstream, high strength, durable, heavy
At present, the mainstream tarpaulins on the market are mostly tarpaulins. Common PVC tarpaulins are made of high-strength polyester filaments. Polyester material has excellent corrosion resistance, abrasion resistance and high strength, and is famous for its good durability. The PVC oilcloth is sprayed with polyvinyl chloride, so that the fabric forms a waterproof layer, which can effectively prevent rainwater from penetrating, and can almost achieve the effect of dripping water.
Although the PVC tarpaulin is excellent in water resistance and abrasion resistance, in terms of weight, the weight of the tarpaulin is still relatively large. Even if it is a 4-meter-2 warehouse grid truck, it will be difficult to cover the tarpaulin when it is operated by one person. It is very strenuous, and it is more suitable for models with a length of less than 9 meters 6.

2. PE tarpaulin

Lightweight, less wear-resistant
If you want a certain degree of water resistance while also wanting to take into account good lightweight, then PE tarpaulin will be a good choice. The production of PE tarpaulin generally adopts color striped cloth, the raw material is high-density polyethylene, and PE film is coated on both sides of PE woven cloth. Its biggest feature is that it is very light, and the price is more affordable, and it also has basic Waterproof effect.
However, the wear resistance of this PE tarpaulin is relatively lacking. If it is often operated under harsh and complicated working conditions, it may be easily damaged after repeated use. Because the weight is light enough and cheap enough, it is relatively common on large trailers, and it is relatively easy to cover. Even if it is damaged, it does not hurt to replace it.

3. Film tarpaulin

Lightweight, durable and waterproof
Now there are more card users who use film tarpaulin. It is characterized by being lightweight and more durable and waterproof than ordinary tarpaulins. This kind of tarpaulin has a layer of anti-wear coating inside, and the tarpaulin adopts a whole design, which can directly cover the cargo compartment.
However, if the film-attached tarpaulin has damaged holes and wants to be repaired, even if it is glued with the best glue, it is prone to instability and falling off.

4. Scraping cloth

Strong wear resistance
Now the use of knife scraping cloth is also popular. This kind of tarpaulin is made of chemically synthesized material and is composed of three parts. The uppermost and lowermost two parts are usually made of PVC materials, and the middle layer is made of light-guiding fiber stickers. The three are compressed together by a specific compression method to form a scraping cloth.
In fact, it can be seen from the name that the knife-scraping cloth has outstanding wear resistance, high strength, good ductility, and strong flexibility. It is not easily affected by corrosion and has a certain waterproof ability. The surface of this kind of knife scraping cloth is very smooth, and it feels good to the touch. It can play a good role in covering and protecting transportation vehicles and open-air goods.

5. Three-proof cloth

Fireproof, waterproof, moldproof
The three-proof cloth is made by coating PVC, PTFE, flame-retardant silica gel and other refractory materials on the surface of refractory fiber, and adding various chemical additives such as anti-mold agent, anti-aging agent, anti-static agent, etc., and heat-sealed at high temperature. It has the function of fireproof, waterproof and mildewproof.
